Filed: 1963-05-22
Abstract: 1,100,532. Filter element. EVANS, ADLARD & CO. Ltd. 19 Aug., 1964 [22 May, 1963], No. 20305/63. Heading B1T. [Also in Division B5] A gas filter comprises a woven, nylon, mesh former (Fig. 5, not shown) having concentric corrugations, on which is deposited a porous layer of randomly oriented fibres. The fibres may be glass, of 0.5-3 microns diameter and sufficiently short not to bridge the corrugations. Other suitable fibres are ceramic, vegetable or synthetic plastics. The former may have a stiffening coating of phenolic resin and an edge-sealing layer of polyvinyl chloride. Fig. 9 shows a former having 6 concentric corrugations round a flat central panel 27 and a smaller former 28 positioned within the panel, prior to depositing the fibres. In manufacture, the former is pressed between two dies (Fig. 2, not shown), the upper one comprising concentric rings which act on the former in order of increasing diameter. The former is annealed while locked between the closed dies. The stiffening resin may be applied before pressing, and itself be cured in the annealing step, or it may be applied after the former is removed from the dies, necessitating an extra, curing, heat treatment. The former(s) is then placed in a duct (Fig. 6, not shown) through which is passed a suspension of fibres in an acid solution, and a gelatinous layer is formed (by the acid) on the fibres so that they adhere together and to the former(s). A former which is not resin-coated may be radially stretched during the fibre depositing step and then allowed to resiliently close up to the desired shape. The filter is for use in respiration, e.g. a gas mask. Corrugation peaks may be more blunt on the coated side, and formed thus by beaded die rings (Fig. 4, not shown).

Title: Improvements in and relating to the preparation of alloys
IPC: C22C1/02
Filed: 1950-08-16
Abstract: A method of preparing alloys from the group consisting of iron, chromium, nickel, cobalt, tungsten and molybdenum comprises melting the metals and maintaining them under vacuum until substantially all gas has been removed therefrom, treating with hydrogen at sub-atmospheric pressure to reduce metallic oxides, adding less than 1 per cent. by weight of an active deoxidising agent while hydrogen is still passing through the melt to remove residual nitrogen and oxygen, discontinuing the hydrogen treatment, heating the melt under gradually reducing pressure to remove the dissolved hydrogen, and casting into a chill mould. The pressure may be less than 10 microns during the first stage, 40 mm. during the hydrogen treatment, and less than 10 microns during the final stage.  The hydrogen may be blown on to the surface of, or bubbled through, the melt.  The deoxidising agents may be titanium, zirconium, aluminium, magnesium, vanadium, silicon, carbon or calcium.  The corrosion rate in molten lead oxide of the alloys produced may be improved by the addition to the melt of titanium, aluminium, zirconium or magnesium as alloying elements.  The hydrogen treatment may be replaced by a treatment with carbon.
